Use electronic scales and an app such as myfitnesspal. Weigh and record everything you eat and drink for a week, and use the app to estimate how many calories you need daily. Then you can see if you are getting it right. It's really hard to guess these things. Alternatively, weigh yourself weekly. Weight going up - portion size too big. Weight going down - portion size too small Simples

I think that's the problem. It gives the illusion of food being 'piled high' but they're small shallow plates so I think I've been misjudging my portions. Put that on a normal plate and it probably wouldn't fill half. I hadn't noticed.

I would say I walk approximately 2 miles a day and then do about an hour of housework a day.
